Thermally Assisted Photocatalytic Dehydrogenation of Methanol in Continuous Steady‐State Operation

Advanced Science, EarlyView.
Thermally assisted photocatalytic methanol dehydrogenation on Pt/TiO2 enables formaldehyde and hydrogen production far beyond thermodynamic limits. Continuous operation delivers up to 95% selectivity over 70 h, and oxygen microdosing strongly boosts conversion by regenerating surface oxygen sites.

Magnetic-Field-Tuned Spin-Dependent D-Band and Bifunctionality in L1₀-FeCoPt for Enhanced Methanol Oxidation. [PDF]

Adv Sci (Weinh)
The d‐band center and bifunctional mechanism jointly regulate the amounts of adsorbed OH* and CO*, thereby enhancing electrocatalytic performance, while the application of an external magnetic field further boosts this performance. ABSTRACT The spin‐dependent electronic structure of transition‐metal alloys plays a key role in tuning the magnetic‐field ...

Electrocatalytic CO2 Reduction over Sn‐Cu Bimetallic Catalysts Synthesized via an Amalgamated Lithium Metal Method

Advanced Science, EarlyView.
An amalgamated lithium metal method enables systematic control of Sn–Cu active‐site dimensions from isolated atoms to nanocrystallites. Increasing the metal loading shifts CO2 electroreduction selectivity from acetaldehyde on highly dispersed Sn–Cu sites to formate on Sn‐rich crystallites, revealing how bimetallic dispersion and local coordination ...

EBV‐Driven ODC1 Upregulation Enhances Polyamine Anabolism to Promote Viral Replication and Cisplatin Resistance in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
EBV‑BZLF1 initiates ODC1‑driven polyamine anabolism that correlates with poor clinical prognosis in nasopharyngeal carcinoma. The ODC1–spermidine axis promotes viral replication, cell proliferation and innate immune evasion. Pharmacological inhibition of ODC1 rescues cisplatin sensitivity, establishing ODC1 as a viable therapeutic target for EBV ...

Electrocatalytic C─C Bond Formation Via Cyanide Interception of CO2 Reduction Intermediates

Advanced Science, EarlyView.
ABSTRACT Electrochemical CO2 reduction offers a sustainable route to convert greenhouse gas into high‐value‐added chemicals, yet product distributions remain largely limited to simple C1‐C3 molecules. Here, we report a new reaction in which CO2 reduction intermediates undergo direct C‐C coupling with an external carbon nucleophile under electrochemical
